Photoshop and other energetic photo editing software has made some photographers think that filters filtering or filters may refer to aren't something they need to attach to lenses anymore. In what way, there are some effects which still look better when created in the real world with the help of a filter. Plus, by engendering the desired effect in-camera, you also save time and it's often easier to achieve the look you're after. (We actually from an interesting article that covers the debate of Physical Filters Vs Photoshop that's well worth a peruse.)
Yes, you can use saturation tools to muddle through skies 'pop' but if you attach a circular polarising filter to the front of your lens, you can see just how deeper the sky looks and how it balances with the scene which means you can perfect your shot without turning your computer on.
We've used the circular polarising drain as an example as this is the filter Jon Adams is talking about in the above video. When you hit 'play' on the tutorial, you'll hear Jon talk at the end of ones tether with the benefits of using polarising filters, why spending a little bit more money on filters is a worth-while investment and he also gives a little step-by-step counsel on capturing a landscape scene.
